centos设置静态ip及出现的问题解决

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
UUID=cb2546d2-05fa-44a2-ac1e-c8fa0a9c1c00
NM_CONTROLLED=yes
BOOTPROTO=none
USERCTL=no
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="eth0"
HWADDR=00:0C:29:C1:30:2A
PEERDNS=yes
PEERDNS=yes
IPADDR=192.168.208.104
NETMASK=255.255.255.0
DNS2=221.11.1.68
GATEWAY=192.168.208.2
DNS1=221.11.1.67
保存
service network restart
如果出现
[root@localhost ~]# service network restart
Shutting down interface eth0: Device eth0 has MAC address 00:0C:29:C1:30:2A, instead of configured address 00:0C:29:F6:52:E4. Ignoring.
[FAILED]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring.
[FAILED]
查看mac地址 cat /sys/class/net/eth0/address
编辑网卡配置文件vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改HWADDR为执行cat /sys/class/net/eth0/address的结果
保存再重启网卡service network restart
[root@localhost ~]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Determining if ip address 192.168.208.104 is already in use for device eth0... [ OK ]
